Abstract: Styrenes such as methylstyrene and dimethylstyrene have been produced by the gas-phase catalytic decomposition at an elevated temperature of 1,1-diarylethanes. In accordance with the invention the decomposition is effected at 300° to 700° C using zeolite as a catalyst. The use of a zeolite catalyst provides greater conversions of the 1,1- diaryiethanes and improved selectivity to the desired styrene.

Abstract: A liquid crystal cell includes a cholesteric liquid crystal between two aligning surfaces. The cell has two stable states (A and C) in which the active region is substantially free from disclinations and walls. The cell can be switched between stable states by applying an alternating electric field to bring the cell to an unstable state (B) from which it relaxes to one or other of the stable states depending on how the field is removed, for example whether it is removed abruptly or gradually. Since both of the stable states are stable, no energy is required to maintain them, only to switch between them. The cell has applications to light valves and displays.

Abstract: 1. Process for the determination of the diameter of a particle in suspension in a fluid by the use of coherent electromagnetic radiation, being a process in which a substantially parallel beam of the said electromagnetic radiation is directed at the said particle, the radiation diffused by the said particle in a selected direction is collected, and the diameter of the particle is determined by utilizing the ratio between the energy diffused in the said direction and the energy of the incident radiation, characterized in that a determination is made, for the material of the particles to be investigated, of a minimum angle of separation between the direction of the axis of the beam and the direction of collection of the diffused radiation, this angle being - proceeding from small angles - beyond the range in which the relation between the diffused energy and the diameter of the particles does not exhibit a sufficient degree of one-to-one correspondence for the quality of measurements under consideration, a direction of collection of the radiation is selected which is separated from the axis of the incident beam by an angle which is at least equal to this minimum angle, and in that there is placed in the path of the incident radiation, before it reaches the particle, a beam correcting system which is computed in order that the energy density of the beam which has passed through the said system is substantially constant over the entire section of the beam with the exception of a peripheral portion in which this density decreases rapidly in a direction away from the axis.

Abstract: Avec le present procede, on augmente considerablement la basicite du laitier de depart et on maintient le laitier a la limite de saturation, si possible pendant tout l'affinage, mais au moins pendant la periode de demarrage critique. Il convient d'atteindre la saturation en MgO et aussi la saturation du laitier en CaO et en disilicate de calcium. Vers la fin du soufflage, on travaille avec une quantite de scories fixe par tonne d'acier pour une teneur en Si determinee dans la fonte brute. On ajoute a la fonte de depart, avant ou pendant le debut de l'affinage, avec les fondants pour la scorification, une certaine quantite de MgO par tonne d'acier en fonction de la teneur en Si de la fonte; apres le debut d'affinage et apres la piquee de l'acier, la totalite du laitier reste dans le convertisseur. Ceci a l'avantage que, d'une part, la duree de la chemise du four est augmentee et, d'autre part, la quantite des fondants necessaires est considerablement reduite. Le reglage du laitier est plus regulier et les resultats metallurgiques sont ameliores.

Abstract: A method for stabilizing organic polymers against copper-catalyzed oxidative decomposition by means of N,N-bis-salicyloyl hydrazine as a metal deactivator is described wherein dust development of the metal deactivator is precluded with certainty and negative property changes of the stabilized organic polymers are avoided. For this purpose, it is provided that a paste which contains finely-crystalline N,N'-bis-salicyloyl hydrazine in fine distribution in a liquid to wax-like aliphatic hydrocarbon of low volatility is worked into the polymer. The method is particularly well suited for stabilizing polyolefins for cable and wire insulation.
